I am looking at implementing an 'intelligent' energy harvesting system using a recently installed system that has PV array and a Pylontech battery bank and the above plus a mppt 150/70, that is to use a certain/calculated amount of stored energy in the evenings, and then restore that with PV sourced electricity via the mppt 150/70 the next day. I have made a seperate contoller to do this, that can monitor the SOC from the Pylontech bank via CAN Bus messages, so that once the SOC quota is used it will go back to AC power. I will activate the Inverter by an external transfer switch to disable the AC in and that will get the Inverter on line.
What I don't want the Inverter / Charger to do is use the main supply to charge the batteries automatically when it comes on again, that will be done by the PV the next day, I know one can switch off "Enable Charger" in the VE Configure but I want to be able to do this via a control signal or software command to the Venus or the Quattro everyday and can't seem to find any way of doing that so far.
I would appreciate any information in this regard.
One way of doing this is to switch OFF the Inverter by the remote control which is easily done but then there would be gaps in the data on the VRM portal since the Quattro monitors the main feed in terms of power supply.
Thanks in advance.
